File extension overrides not working.

[1BADragon]

Summary

File overrides in languages.toml are not taking for file extensions for pre-associated types. Specifically I want C header files (.h) to have language C but helix is setting the language to CPP even with the following language config:

[[language]]
name="c"
scope="source.c"
auto-format=true
file-types = ["h", "c"]

Reproduction Steps

I tried this:

Using this config

[[language]]
name="c"
scope="source.c"
auto-format=true
file-types = ["h", "c"]

I expected this to happen:
open .h file and have language set to "c"

Instead, this happened:
language was set to "cpp"

You also need to remove the h file-type from C++'s configuration:

helix/languages.toml

Lines 438 to 445 in d570c29

	[[language]]
	name = "cpp"
	scope = "source.cpp"
	injection-regex = "cpp"
	file-types = ["cc", "hh", "c++", "cpp", "hpp", "h", "ipp", "tpp", "cxx", "hxx", "ixx", "txx", "ino", "C", "H", "cu", "cuh", "cppm", "h++", "ii", "inl", { suffix = ".hpp.in" }, { suffix = ".h.in" }]
	comment-token = "//"
	language-servers = [ "clangd" ]
	indent = { tab-width = 2, unit = " " }

For example:

# ~/.config/helix/languages.toml
[[language]]
name = "cpp"
file-types = ["cc", "hh", "c++", "cpp", "hpp", "ipp", "tpp", "cxx", "hxx", "ixx", "txx", "ino", "C", "H", "cu", "cuh", "cppm", "h++", "ii", "inl", { suffix = ".hpp.in" }, { suffix = ".h.in" }]

Thanks that worked.

I suppose I'd expect a user specified extension to override any built ins.
